  Subsequent STEP2 to STEP4 are processing by the enlarged index display unit 12. The enlarged index display unit 12 determines whether or not the contact of the indicator of the initial index 50 is detected by the contact position detection circuit 21 in STEP 2 (whether or not the user performs a touch operation on the initial index 50). Judging.

  Then, when contact of the indicator with the initial index 50 is detected, the process proceeds to STEP 3 and the enlarged index display unit 12 displays the enlarged index 60 as shown in FIG. In the example of FIG. 5, the expanded index 60 is an expanded item button of “tap” obtained by enlarging the “tap” item button 51 h (selection item button) of the initial index 50 in contact with the user's finger F to the first size. 61h (enlargement selection item button) is displayed.

  5 to 8, the enlarged item button 61 of the same item enlarged by the enlarged index 60 is replaced with the same alphabet in the item button 51 (51a to 51s) of the initial index 50 shown in FIG. It is attached.

  Further, the enlarged index display section 12 has six item buttons 51 (peripheral item buttons) consecutive in the vertical direction from the “tap” item button 51h in the initial index 50 (corresponding to the first predetermined number of the present invention). The item button 51g of the “reamer” continuous in the upward direction and the item button 51f of the “chamfering / centering”, the item button 51i of the “milling cutter / cutter” continuous in the downward direction, and the item of “cutting tool” An enlarged item in which the button 51j, the “tooling” item button 51k, and the “tooling” item button 51l are enlarged to a size that gradually becomes smaller than the enlarged item button 61h as they are separated from the “tap” enlarged item button 61h. The buttons 61f, 61g, 61i, 61k, 61l are arranged in the same order as the initial index 50. Shimesuru.

  In this way, when the initial index 50 is touch-operated, the selection item button is set to the largest size starting from the touch-operated item button 51 (selection item button, “tap” item button 51h in FIG. 5). It is selected for the user by enlarging (enlarged item button 61h in FIG. 5), and displaying the enlarged index 60 enlarged to a size that gradually decreases as the surrounding item button 51 is moved away from the selection item button. The item can be easily viewed.

  Further, the user can intuitively recognize where the other items in the vicinity of the selected item are in the electronic book by the difference in the size of the enlarged item button.

  In subsequent STEP 4, the enlarged index display unit 12 displays the page of the item of the electronic book (tap in FIG. 5) selected by the touch operation of the enlarged index 60 on the touch panel display unit 20.

  STEP 10 to STEP 11 branched from the next STEP 5 and STEP 5 are processes by the expansion index changing unit 13. In STEP 5, the enlarged index changing unit 13 determines whether or not the indicator in contact with the enlarged index 60 has been slid in the vertical direction by the contact position detection circuit 21 (whether the user has performed a slide operation on the enlarged index 60). Judging. If a vertical slide is detected, the process branches to STEP 10. If a vertical slide is not detected, the process proceeds to STEP 6 in FIG.

  In STEP 10, the enlarged index changing unit 13 displays the enlarged index 60 by enlarging the enlarged item button 61 (enlarged selection item button) in contact with the indicator to the second size, and at the initial index 50. 7 items buttons 51 (corresponding to the second predetermined number of the present invention) consecutive from the item buttons 51 (item buttons having the same assigned item) 51 corresponding to the enlarged selection item buttons are selected and enlarged item buttons. An enlarged item button (enlarged surrounding item button) enlarged to a size that becomes smaller as the user leaves is displayed (enlarged shift display).

  The processing of STEP 5 and STEP 10 to STEP 11 by the enlarged index display unit 12 corresponds to the enlarged index display step in the electronic book browsing support method of the present invention.

  For example, in FIG. 6B, from the state where the user's finger F touches the “tap” enlarged item button 61h shown in FIG. 6A, the finger F is slid upward to touch the “reamer” enlarged item button 61g. It shows the case of transition to the state. In this case, the enlarged index changing unit 13 sets the enlarged item button 61g of “reamer” to the largest size, and moves the surrounding enlarged item buttons 61e to 61f and 61h to 61k away from the enlarged item button 61g of “reamer”.
